From 2a5bbbeaaef5372a1c5417fd517403acb9fc61fd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Gerg=C5=91=20Magyar?= Date: Fri, 29 May 2026 20:04:41 +0100 Subject: [PATCH] fix: make extension installs offline-first (#1161) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(review): add PR reviewer swarm agents Seven read-only subagents coordinated by an orchestration skill for structured, evidence-grounded production-readiness PR reviews. Agents: facts-historian, branch-hygiene, risk-architect, test-ci-verifier, security-boundary, docs-dod, synthesis-critic. All use Read/Grep/Glob/Bash only — no edit tools. Skill invoked as /gitnexus-pr-swarm-review . * fix: patch vector extension and uncaughtException for review findings - Add { policy: 'auto' } to both loadVectorExtension() calls in embedding-pipeline.ts so analyze --embeddings auto-installs VECTOR - Add void to uncaughtException shutdown(1) call for Node v20+ safety - Re-add getExtensionInstallPolicy export + default change + 4 tests * fix(mcp,lbug): graceful shutdown exit codes + complete offline-first VECTOR policy Completes the two live issues PR #1161 only partially addressed. #1132 — MCP shutdown crash: SIGINT/SIGTERM were registered with `shutdown` directly, so Node passed the signal NAME string into process.exit(), crashing with ERR_INVALID_ARG_TYPE ('SIGTERM'). Map signals to numeric exit codes (SIGINT->130, SIGTERM->143) via a testable installSignalShutdown(); add an unref'd force-exit watchdog so a hung disconnect()/close() cannot wedge shutdown; and void the stdin/stdout handlers so event payloads never reach process.exit() as a non-number. #1153 — offline-first extension loading: - semanticSearch (a query/read path) no longer forces policy:'auto'; queries use load-only and never spawn a network INSTALL (extension.ladybugdb.com). - the analyze embedding WRITE path resolves the policy from GITNEXUS_LBUG_EXTENSION_INSTALL (honoring never/load-only/auto; default auto) instead of hard-forcing 'auto', so an offline/locked-down operator's override is respected (the regression that re-broke #1153 for the VECTOR path). - surface the active install policy in `gitnexus doctor` (was claimed but never delivered; also gives the previously-dead getExtensionInstallPolicy a caller). - emit an actionable message when VECTOR is unavailable. Tests: regression for the signal->numeric mapping (reproduces the signal-string crash condition) and for embedding install-policy resolution. tsc/prettier clean, eslint 0 errors, 55 unit tests pass. Co-Authored-By: Claude Opus 4.8 (1M context) * fix(analyze): degrade gracefully when FTS extension is unavailable The load-only default made `gitnexus analyze` throw when the FTS extension was not pre-installed, breaking CI and offline use. Make the analyze write path opt into the `auto` install policy (LOAD-first then bounded INSTALL — symmetric with the VECTOR/embeddings path and the #726 contract) and degrade gracefully when the extension still cannot load: skip search-index creation, log a warning, and complete with a fully queryable graph (only full-text/BM25 search is disabled). `--repair-fts` still fails loudly. - Surface the degraded state instead of reporting healthy: AnalyzeResult.ftsSkipped, a persistent CLI summary warning, and meta.json capabilities.fts.status = "unavailable". - Skip the FTS-primitive integration tests when the extension is unavailable (shared skipUnlessFtsAvailable helper). - Add a unit test for the degradation branch; fix the existing full-analyze test mock that omitted loadFTSExtension. Co-Authored-By: Claude Opus 4.8 (1M context) * test(lbug): skip FTS-seeding suites when extension is unavailable The withTestLbugDB helper seeds FTS indexes in beforeAll via createFTSIndex, which throws when the optional FTS extension cannot load — failing the whole suite on machines where it is neither pre-installed nor installable (the macOS platform-sensitive CI runner). Probe the extension once (mirroring the analyze write path's `auto` policy), bypass FTS seeding when it is unavailable, and skip the suite's tests via beforeEach with a one-time warning so the skip is visible rather than a setup crash. Fixes the macOS failures in search-core, search-pool, local-backend-calltool, and staleness-and-stability. Suites still run normally where FTS is available.
